Robert is working two summer jobs, making $10 per hour babysitting and making
$25 per hour tutoring. In a given week, he can work no more than 10 total hours and
must earn a minimum of $130. If Robert worked 4 hours tutoring, determine the
minimum number of whole hours babysitting that he must work to meet his
requirements. If there are no possible solutions, submit an empty answer.
Answer:
3 hours
Step-by-step explanation:
The equation will be
10b+25t ≤ 130 (b = hours of babysitting, t = hours of tutoring)
Plug in the 4 hours of tutoring
10b+(25 times 4) ≤ 130
= 10b+100 ≤ 130
10 times 3 = 30, which answers the question
Since 100 + 30 = 130
Therefore, the answer to the minimum amount of hours Robert has to tutor
to make a minimum of $130 is . . .

Ms. Avella’s class volunteers at an animal shelter one day per week.each student is responsible for caring for four animals during every hour spent at the shelter
Please help
Answer:
Option (3)
Step-by-step explanation:
Since, every student is responsible for the caring of 4 animals during every hour,
Number of animals cared for ∝ Number of hours spent at shelter
a ∝ h
a = kh
Here 'k' = proportionality constant
For h = 1 and a = 4,
k = [tex]\frac{h}{a}=\frac{4}{1}[/tex]
k = 4
a = 4h
By this equation,
For h = 2,
a = 8
For h = 3,
a = 12
For h = 4,
a = 16,
For h = 5,
a = 20
Since, for every input value there is a different output value,
Diagram shows a function.
Therefore, Option (3) will be the correct option.

M is the midpoint of RS. R has coordinates (-2,-3) and M has coordinates (1,0). Find the coordinates of S.
Answer:
[tex](4,3)[/tex]
Step-by-step explanation:
Given
[tex]R = (-2,-3)[/tex]
[tex]M = (1,0)[/tex]
Required
Determine the coordinates of S
Midpoint is calculated as:
[tex]M(x,y) = \frac{1}{2}(x_1 +x_2,y_1+y_2)[/tex]
Where:
[tex](x,y) = (1,0)[/tex]
[tex](x_1,y_1) = (-2,-3)[/tex]
Substitute these values in the above formula:
[tex](1,0) = \frac{1}{2}(-2 + x_2,-3+y_2)[/tex]
Multiply through by 2
[tex]2 * (1,0) = 2 * \frac{1}{2}(-2 + x_2,-3+y_2)[/tex]
[tex](2,0) = (-2 + x_2,-3+y_2)[/tex]
By direct comparison:
[tex]2 = -2 + x_2[/tex] and [tex]0 = -3 + y_2[/tex]
Solving for x2
[tex]2 = -2 + x_2[/tex]
[tex]x_2 = 2 + 2[/tex]
[tex]x_2 = 4[/tex]
Solving for y2
[tex]0 = -3 + y_2[/tex]
[tex]y_2 = 0 + 3[/tex]
[tex]y_2 = 3[/tex]
Hence, the coordinates of S is: [tex](4,3)[/tex]

Halla el perímetro y el área de un rectángulo cuyos lados miden 6,3 dm y 48 cm respectivamente
Answer:
El perímetro y el área de un rectángulo cuyos lados miden 6,3 dm y 48 cm es 222 cm y 3024 cm² respectivamente.
Step-by-step explanation:
Para empezar debes tener en cuenta que las medidas tienen que estar en la misma magnitud; por lo tanto en este caso la unidad de medida elegida a utilizar es centímetros. Por lo que el lado que mide 6,3 dm será expresado en cm. Entonces se puede aplicar la siguiente regla de tres simple: si 1 dm equivale a 10 cm, entonces 6,3 dm a cuántos cm equivale?
[tex]cm=\frac{6,3 dm*10 cm}{1 dm}[/tex]
cm=63
Entonces 6,3 dm= 63 cm
El perímetro es la distancia alrededor de una figura, mientras que el área es las unidades cuadradas dentro de una figura.
El Perímetro de un rectángulo es igual a la suma de todos sus cuatro lados. Un rectángulo siempre tiene dos pares de longitudes iguales. Entonces en este caso se obtiene:
63 cm + 63 cm + 48 cm + 48 cm= 222 cm
El área de un rectángulo es el producto de la longitud de los lados. Entonces en este caso se obtiene:
63 cm* 48 cm= 3024 cm²
El perímetro y el área de un rectángulo cuyos lados miden 6,3 dm y 48 cm es 222 cm y 3024 cm² respectivamente.

Step-by-step explanation:
A movie theater complex gave a poll as viewers exited from two theaters showing the same film. They had a 20% response rate from the people in theater A and a 30% response rate from the people in theater B. There were 800 people in total in theaters A and B.
Part A: It was estimated that an equal number of people from each theater responded to the poll. If this was the case, how many people in total would have been in theater A?
Part B: In reality, 440 people were in theater A and 360 people were in theater B. What was the total response rate for the poll? Express your answer as a percentage.
Answer:
Let´s define the variables:
x = number of people in theater A
y = number of people in theater B
We know that a 20% (or 0.2 in decimal form) of the people in theater A answered the survey, then the number of people from theater A that answered the survey is: Na = 0.2*x
We know that a 30% (or 0.3 in decimal form) of the people in theater B answered the survey, then the number of people from theater B that answered the survey is: Nb = 0.3*y
There where 800 people in total (counting from the two theatres)
Then x + y = 800.
A) In this case we have:
Na = Nb
this means that:
0.2*x = 0.3*y
and we also have the equation:
x + y = 800
To solve this, we need to isolate one variable in one of the equations, i will isolate x in the second equation:
x = 800 - y
And now we can replace this in the other equation to get:
0.2*(800 - y) = 0.3*y
We need to solve this for y:
160 - 0.2*y = 0.3*y
160 = 0.3*y + 0.2*y = 0.5*y
160/0.5 = y = 320
Then there where 320 people in theater B, and:
x + y = 800
x + 320 = 800
x = 800 - 320 = 480
There where 480 people in theather A.
B) Now we have:
x = 440
y = 360
then:
Na = 0.2*440 = 88
In theater A, 88 people answered the survey.
Nb = 0.3*360 = 108
In theater B, 108 people answered the survey.
In total, 88 + 108 = 196 people answered the survey.

Mr.Sanchez bought 2 magazines for $9.95 each and 1 book for $14.95. If the sales tax is 6%, what is the total cost of Mr.Sanchez’s purchase?
Answer:
36.94
Step-by-step explanation:
Multiply 34.85 (the total cost of the book and mags) by 0.06 (cost of sales tax) = 2.91
34.94 + 2.91 = 36.94
Find the critical value zα2/ that corresponds to a 91% confidence level. Question 13 options: a) 1.7 b) 1.95 c) 1.81 d) 2.33 e) 2.57
Answer:
D
Step-by-step explanation:
2.33 I think
The critical value that corresponds to a 91% confidence level is 1.7
What is critical value?'Critical value is a cut-off value that is used to mark the start of a region where the test statistic, obtained in hypothesis testing, is unlikely to fall in. In hypothesis testing, the critical value is compared with the obtained test statistic to determine whether the null hypothesis has to be rejected or not.'
According to the given problem,
Confidence level = 91%
Now, α = ( 100 - 91 ) %
= 9%
= 0.09
Area of each tail = [tex]\frac{0.09}{2}[/tex]
= 0.045
Area in the middle = 1 - 0.045
= 0.955
Now, if we look up this area on the z-table, the critical value will come as 1.6954, which is nearly equal to 1.7.
Hence, we can conclude, the critical value is 1.7.

Two groups separately performed an experiment by tossing a coin in the air. Group X performed 50 trials and group Y performed 100 trials. Each group recorded the results in the table below: Group Heads Tails X 33 17 Y 53 47 What conclusion can be drawn about the number of trials and the probability of the coin landing on heads or tails? The experimental probability is closer to the theoretical probability for group Y than group X. The experimental probability and the theoretical probability for group X is the same. The experimental probability and the theoretical probability for group Y is the same. The experimental probability is closer to the theoretical probability for group X than group Y.
Answer:
D. The experimental probability is closer to the theoretical probability for group H than group G.
With any experimental probability, the more trials that are done will make the experiment move more likely to be the theoretical probability. in this case, the theoretical probability for flipping a coin is 50 heads 50 tails which H is closer to. any statistical data the more data collected the more close to reality it is.

Step-by-step explanation:
it given that sin(-x) = -m where x is acute angle . express sec x in terms of m
Answer:
[tex]\sec(x)=\frac{1}{\sqrt{1-m^2}}[/tex]
Step-by-step explanation:
We know that:
[tex]\sin(-x)=-m[/tex]
First, since sine is an odd function, we can move the negative outside:
[tex]=-\sin(x)=-m[/tex]
Divide both sides by -1:
[tex]\sin(x)=m[/tex]
We will now use the Pythagorean Identity:
[tex]\cos^2(x)+\sin^2(x)=1[/tex]
Substitute m for sine:
[tex]\cos^2(x)+m^2=1[/tex]
Solve for cosine:
[tex]\cos^2(x)=1-m^2[/tex]
Take the square root of both sides:
[tex]\cos(x)=\pm\sqrt{1-m^2}[/tex]
Since x is an acute angle, cosine will always be positive. Thus:
[tex]\cos(x)=\sqrt{1-m^2}[/tex]
Take the reciprocal of both sides. Hence:
[tex]\frac{1}{\cos(x)}=\sec(x)=\frac{1}{\sqrt{1-m^2}}[/tex]
